🌟Introducing Chat with NeRF📸: An open-source project that enables chatting with 3D rooms and objects in NeRF! The pipeline combines the capabilities of GPT-4, LLaVA, BLIP-2, nerfstudio, and LERF. Plus, you can even chat with your own scenes by scanning them on your phone!📱1/🧵
Thrilled to have contributed to the major update of the @buildingSMARTIn Validation Service! It's rewarding to see our efforts come to fruition 🏗️🏡
validate.buildingsmart.org just received a major update Validates your models wrt: - syntax - schema (incl where rules and functions) - additional rules - consistency with bsdd Valid and reliable data is the cornerstone of our industry.
Over the past years, IFC has become geometrically more simple and explicit. IfcOpenShell, sitting on a heavy geometry kernel, was late to adapt to that. But here we are now, conversion time is decimated for explicit ReferenceView models. Read on below.
Anybody here still on twitter? 🎉We're getting closer to a feature complete express where rule and function to python compiler in IfcOpenShell🎉 Express on the left and generated python on the right.
Yes. Go #OpenBIM. Go #OpenSource. Matthew Fuller shows us how he uses the #BlenderBIM Add-on and #BlenderKit to do #Scan2BIM. Share more at @OSArchOrg
For a large part maybe IfcOpenShell is pedestrian. Reading and writing files in ancient standards isn't that sexy But has also brought ML on building models, 2D drawing generation, continuous integration on designs, transactional APIs, voxel-based compliance checking, ...
Reconstruction of a window from a single picture itc.scix.net/paper/w78-2021… The window and the wall are also stored in an IFC file.
📢Check out our new @NeurIPSConf paper in collaboration with @NVIDIAAI!!! ATISS is a novel transformer architecture that advances the state-of-the-art of scene synthesis while enabling a number of interactive applications with versatile user input. nv-tlabs.github.io/ATISS
Artur presenting the IfcOpenShell Google summer of code project on bSI Information Delivery Specifications at the CIB w78 code compliance workshop
Soon at the CIB w78 conference: Multi-disciplinary learning from OpenBIM, presented by Tim McGinley. Paper: itc.scix.net/paper/w78-2021… An integrated ecosystem of BIM courses at DTU with automated feedback loops between design and code compliance courses.
Soon at the CIB w78 conference: Towards automatic construction of photorealistic BIM window elements from single-picture input. Presented by @LuttunJ Paper: itc.scix.net/paper/w78-2021… BIM for existing buildings is huge opportunity. We show derivation of 3D bim from a single image.
IfcOpenShell can now automatically generate SVG plans and elevations from any IFC model created with the Homemaker add-on
The new IfcOpenShell academy is live! academy.ifcopenshell.org Creating content never was easier! Just create Markdown or a Jupyter Notebook here github.com/IfcOpenShell/a… and thanks to Nikola it'll be converted automatically into a post using Github Actions.
Yes. Go #OpenBIM. Go #OpenSource. Did you ever want transactioned high-level #NativeIFC operations with undo and redo support out of the box? With #IfcOpenShell, now you can.
Go #OpenBIM. Go #OpenSource. 100% free #BlenderBIM Add-on new v0.0.210605 with OVER 100 new features! Supported by #EpicMegaGrants & #GoogleSummerOfCode, check out new #Parametric authoring, #4D scheduling, #5D costing, & structural features! Get it today: blenderbim.org
Using the so-called Medial Axis Transform we can rebuild a directed spatial connectivity graph from the voxelized flow field. This yields a more topologic view so that we can count the number of routes to a space.
For a clearer understanding, here is the unmasked distance field for the two floors in this model.
After the bSI awards, this is another amazing recognition for @BlenderBIM and #IfcOpenShell These funds will be put to good use: drawing generation that all OpenBIM tools can leverage, @LuttunJ finalizing his real-time geometry processing test bed and multidisciplinary goodness
Yes. Go #OpenBIM. Go #OpenSource. Incredibly thrilled to announce that the #BlenderBIM Add-on is an #EpicMegaGrants Recipient! Funds will be invested for 100% free software to benefit the entire AEC industry & provide Native IFC BIM software for everyone. osarch.org/2021/05/25/epi…
